PECULIARITIES: Nishikawa
et al. (1999) compared nuclear ribsomal DNA (internal transcribed spacer region)
of 55 species. They found that subsection 6b of the Trumpets may be more closely related to the Asiatics;
in contrast, subsection 6a seems to have more affinities to the
together with L. henryi.

The closely related L.
zairii, an endemic of Central Africa (Congo and Burundi) seems to be
nothing else than a naturalized selection of L. formosanum.

CULTURE NOTES: Not winter-hardy, best grown
in a cool greenhouse where it can grow constantly forming offsets, resulting in
year-round flowering. It is rather short lived and also suscpetible to virus,
but easily renewed by seeds and offsets. Seedlings may flower for the first time
6-8 months after sowing.
